An apparatus is provided for rotational equipment. This apparatus includes a rotor blade including an airfoil body, a spar structure and a cuff. The airfoil body extends spanwise from a base to a tip. The airfoil body extends longitudinally (e.g., chordwise) from a leading edge to a trailing edge. The airfoil body extends laterally between a first side and a second side. The spar structure extends spanwise within and supports the airfoil body. The cuff projects out from the spar structure and away from the base of the airfoil body. The cuff is formed integral with the spar structure. The cuff and the spar structure are configured from or otherwise include thermoplastic material.
